Recall the engine presently in my Pantera came from my Mach I, which
had a flexplate and automatic transmission. The engine had been
balanced for that car/trans combination. When I refreshed it three
years ago, I replaced rings, bearing and gaskets, that's all. So it
was still essentially balanced for the flexplate and auto trans.<br clear="none">
<br clear="none">
The flywheel is from the original engine, still on the engine
stand. So no, this flywheel was not balanced with the present
engine. That's why the shop wants me to bring the flexplate (from
the original build) and the flywheel/clutch. They'll check the
balance of the flexplate and try to match the flywheel and clutch.<br clear="none">
<br clear="none">
During the SSCC run of 2013, it had a noticeable vibration. After
thinking about it more, I believe it's a imbalance in the
flywheel/clutch. I still have some troubleshooting to do to get
more comfortable with that being the cause, but I think it is.<br clear="none">
<br clear="none">
My other option is to build a whole new engine (stroker, solid
roller cam, blah, blah, blah) <insert evil genius laugh here>
and have it all balanced properly from the get-go. :)<br clear="none">

From the Pantera Research Institute - Pacific Northwest
chapter.<br clear="none">
<br clear="none">
Today I called around looking for a place that could
balance my flywheel <br clear="none">
and clutch. I found one. He reiterated that I needed to
be sure the <br clear="none">
vibration was engine speed related, i.e. do I get the same
vibration in <br clear="none">
every gear at the same rpm? I've only managed to drive
the Pantera a <br clear="none">
couple of times and not been focused on the vibration
aspect. I'll <br clear="none">
definitely get out to do that once the weather gets better
and the <br clear="none">
driveway dries up (it's a bit on the muddy side at the
moment).<br clear="none">
<br clear="none">
He said to bring in the flex plate that was part of the
engine setup <br clear="none">
previously, and the flywheel and pressure plate. For
about $70 and a <br clear="none">
week, he said he can balance it all up for me.<br clear="none">
<br clear="none">
All I have to do is pull the ZF to get at it all. Seems
that while I'm <br clear="none">
in there, maybe I should replace the flywheel and clutch
with something <br clear="none">
even better. But then again, what I have in there now is
only a few <br clear="none">
years old. Stock heavy flywheel and a Mcleod clutch. I
should probably <br clear="none">
stick with what I have.<br clear="none">
<br clear="none">
Besides, if I'm going to do the deed this year, I'll need
new tires and <br clear="none">
maybe a new carb. Hopefully gas prices stay low. :)<br clear="none">
